Fast‐Response and Flexible Triboelectric Pressure Sensors with Hierarchical Triple‐Scale Structure for Wireless Smart Seat Detection

), a broad pressure detection range (0.02-53.3 kPa), fast response (16.6 ms), and excellent long-term stability, making it suitable for sustainable self-powered sensing applications. Finite element simulations reveal that larger microstructure sizes and sparser spatial distributions lead to greater deformation, thereby increasing contact area and enhancing charge transfer. These findings align well with experimental results and provide valuable insights for the structural optimization. The PS-TENG's energy harvesting capability is validated by powering light-emitting diodes and a digital hygrothermometer. When integrated with IoT technology, it enables a wireless smart seat detection system for real-time seat occupancy monitoring and public resource management.
